Question says that Wong’s Garage buys quarts of motor oil by the gross (144 units) for $0.75 per quart.

That means cost of 1 quart motor oil = $0.75

Now it says that Wong’s changes the oil in customers’ cars and marks up the oil 175% of the cost.

So that means selling price of the 1 quart of the motor oil

= 175% of original price

= 175% of 0.75

= 1.75* 0.75

= 1.3125

Which is approx $1.31

Hence final answer is $1.31
